Odyssey Marine Exploration, Inc. (OMEX), a pioneer in the field of deep-ocean shipwreck exploration, will visit the NASDAQ MarketSite in New York City's Times Square to celebrate its recent prominent discoveries of the SS Gairsoppa and SS Mantola shipwreck sites.

In honor of the occasion, CEO Gregory Stemm will ring the Opening Bell.

Odyssey Marine Exploration, Inc. (Nasdaq:OMEX) is engaged in deep-ocean exploration using innovative methods and state-of-the-art technology. The Company is a world leader in shipwreck exploration, conducting extensive search and archaeological recovery operations on deep-ocean shipwrecks around the world. Odyssey also has a minority ownership stake in Neptune Minerals, a company focused on discovering and commercializing high-value mineral deposits from the ocean floor. Odyssey also provides contracting services, including proprietary deep-ocean expertise and equipment, to governments and companies around the world.

Odyssey recently located the shipwreck of the SS Gairsoppa, which sank in 1941 carrying a reported cargo of up to seven million ounces of silver. The company has also recently announced the discovery of the shipwreck of the SS Mantola which sank in 1917 with an estimated 600,000 ounces of silver on board. The Company discovered the Civil War-era shipwreck of the SS Republic® in 2003 and recovered over 50,000 coins and 14,000 artifacts from the site nearly 1,700 feet deep. In May 2007, Odyssey announced the historic deep-ocean treasure recovery of over 500,000 silver and gold coins, weighing 17 tons, from a Colonial-era site code-named "Black Swan." In February 2009, Odyssey announced the discovery of Balchin's HMS Victory. Odyssey also has other shipwreck projects in various stages of development around the world.

Odyssey offers various ways to share in the excitement of deep-ocean exploration by making shipwreck treasures and artifacts available to collectors, the general public and students through its webstore, exhibits, books, television, merchandise, educational programs and virtual museum located at www.odysseysvirtualmuseum.com.

Odyssey's shipwreck operations are the subject of a Discovery Channel television series titled "Treasure Quest," produced by JWM Productions. The 12-episode first season aired worldwide in 2009.
